UDD406A ABB cards are sold as genuine products with a one-year warranty

Description

The UDD406A ABB card is in the redundant controller. Any MSG command executed during the switching process will cause errors. (The ER bit of the command will cause
Yes.) After the handover, normal communication will be restored.
Any MSG instruction sent to the redundant controller from the controller in another rack to the redundant controller needs to check Cache Connection:

During switching, the status bit update of the information command is not synchronized with the program scanning. As a result, it is not possible to cross load the status bits of information commands into
Slave controller.
When switching, all active information commands will be inactive. In this case, the new master controller
The execution of the reinitialize information command in the controller.
The scrolling display will change from CMPT indicating compatibility to Qfng indicating that qualification is being granted.
·If the configured information is cache connection, the UDD406A master controller will automatically establish the connection without any error.
·If the configured message is non cached connected or not connected, the master controller will receive “Error 1 Extended Error 301, None
Buffer memory “.

All backplane communications will stop. This abort allows the redundant controller to perform the switchover or diagnostics required to receive information commands.
Important note: If any information is active during switching, one of the following situations may occur:
·Cached and connected messages cause the message command to pause for 7.5 seconds because the controller being launched has not yet
A response was received in the controller. For cached connected information, the information instruction will attempt to execute three more times, each time
Will pause for 7.5 seconds. If the target controller still does not respond to the starting controller after 30 seconds, switch
The connection timeout error “Error 1 Extended error 203” will be given.
For example, the connected information will become the read write information of the CIP data table after the connection is established
·If the non cached connection information is just started, an error will occur after 30 seconds because the
The controller has never received a reply to a forward open request. This error code is “error 1F extended error 204”, namely
Non connection timeout.
For example, unbuffered connection information includes CIP Generic information and captured information during the connection process
Caching connection information will run error free when qualifying. The connection has been established.
Connected, but the information of non buffered connection or non connection will give an error. The error is “error 1 extended error
301, no buffer memory “.
